COIN-OPERATED PHOTOGRAPHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 438,261, dated October 14, 1890.

Application filed April 8, 1890.

To all whom it may concern.-

Be it known that I, PIERRE V. W. WELSH, of New York, in the county and State of-New York, have invented certain new and useful Improvements in Coin-Operated Photographing-Machines, of which the following is a deseription sufliciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of my improved photographic machine, showing the lens-tubes and exposure mechanism; Fig. 2, a front elevation of the machine, the case being removed; Fig. 3, a side elevation lookingfrom the left in Fig. 2; Fig. 4, a top plan view, the feed-box being removed; Fig. 5, a sectional side elevation, looking from the right in Fig. 2; Fig. 6, a vertical longitudinal section of the main shaft; Fig. 7, a perspective view of the developing-carriage; Fig. 8, a like view of the plate-box, the lens-tubes being removed; Fig. 9, an elevation showing the carriage upset and the plate in the bath; Fig. 10, a sectional elevation of the plate escapement mechanism; Figs. 11 and 12 respectively front and rear elevations of portions of the plateside, and Fig. 13 a plan view of the plate feedbox.

Like letters and numerals of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to a photographing-machine actuated by a coin and adapted to automatically make the exposure, develop, and finish the picture; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A representsthe case, which is provided with a coin-slot b, and through which the tubes (Z, containing the ordinary photographing-machines, protrude.

B is a rectangular metallic frame, which Serial No. 347 050. (No model.)

supports the operating mechanism andis disposed in the case. A vertically-disposed plate (3 is secured to the front of the frame, and is provided on its inner face with a longitudinally-arranged dovetail groove which forms ways in which the plate-carriers D slide. A rectangular opening f (see Fig. 2) is formed in the outer face of the plate 0 into the carrier track or ways, said opening being designed to expose the rectangular sensitive plate g. An opening h (see Fig. 8) is formed in the edge of the carrier-track to permit the plate g to be withdrawn from said carrier. A bell-shaped tube 7 projects outward from the track-plate 0, around the opening f, and the lens-tubes d are secured thereto.

The carrier D (see Figs. 11 and 12) consists of a rectangular plate fitted to slide in the track 0. The carrier is supported in its track by an escapement mechanism, (shown in Fig. 10,) the operation of which is hereinafter described. A series of laterally arranged grooved bars j are secured to the inner face of the carrier, said bars forming ways in which the sensitive plates 9 are disposed. An edge of the carrier between the ways j is beveled at 7a to permit a clamp 011 the developing-carriage E, to be projected through the opening or slot h and grasp said plates g. Studs Zare secured at suitable distances to the outer face of the carrier and engage the supporting-bar of the carrier-escapement, alternate studs being arranged at opposite sides of the center line at of said face, as shown in Fig. 12.

The carrier feed-box F (see Figs. 2 and 13) is mounted on the frame B above the carriertrack (J, and is fitted to rotate in frame-bars p. The box comprises a rim q, in which twelve equidistant vertically-arranged chambers r are formed, adapted to register consecutively with the carrier-track groove and severally fitted to receive a carrier D, which is discharged by gravity therefrom into said track. The rim qis supported by radial rods or spokes 5 on a spindle t, rotating in the frame-bars p, A spiral spring 3/ on one of said bars has an end secured to said spindle, whereby the feed-box may be rotated. The inner walls of the chambers r are slotted vertically at c to receive the studs Z on the carriers. A carrier D, provided with twelve sensitive plates is disposed in each chamber ICO r, their lower ends resting on a plate won the the frame, as shown in Fig. 2. The carrier in the chamber registering with the track 0 rests on the upper end of the carrier already in said track and follows it as it descends; A stop 00, Fig. 2, checks the rotation of the box by the spring y after a carrier has been discharged therefrom into the track when the carrier in a succeeding chamber arrives over said track.

A vertically-arranged rotary shaft H (see Fig. 6) is journaled centrally in the frame on cone-bearings 15. Aroundsaid shaft a horizontally-arranged developing-tank K is secured, said tank being supported by brackets 16 on the frame B. The tank is segmental, and one end thereof terminates just below the plate-slot h in the track-plate (J. The 0pposite end of said tank terminates at a platedischarge chute 17, (see Fig. 4,) which projects through the side of the case adjacent to the lens. The tank is divided by partitions 18 into compartments adapted to contain the various liquors or washes employed in developing the picture on the sensitive plates. A horizontal plate 19 is mounted on a flanged sleeve 20 on the shaft H above the tank and carries the developing-carriage E on the outer end of its long arm and a counter-balance 21 on its short arm.

The carriage E is constructed of two parallel tracks or ways 25, arranged laterally on the plate 19 and pivoted at 26 to swing vertically, as shown in Fig. 9. A plate 27 is fitted to slide longitudinally in the ways and bears a block 28, on the inner end of which are two laterally-projecting arms 29 and 30, which engage a fixed cross-piece 31, connecting said ways. A clamp P, consisting of two horizontally-arranged arms 32 and 33, passes through the block 28, the arm 33 being fixed and the arm 32 pivoted in said block. Each arm is provided with a clamping-head 34, adapted to enter the plate-slot h and grasp the plate 9. A spring between said arms tends to hold-said heads together. A coiled spring 35 connects the arch 31, and an arm on the block 28, said spring acting contractively to return the clamp after having been projected into the slot. The opposite ends of the clamping-arms are beveled at 37. (See Fig. 7.) A latch 38 is pivoted in a groove 39 on the arm 33 and slides in a corresponding groove in the companion arm. A flat spring 40 on the latch-pivot acts to force its free end into engagement with the edge of the groove 39 and lock said arms together, separating their heads 34 against the force of the spreading spring. The carriage is prevented from tilting by a vertical latch 41, pivoted to the plate 19 and taking on a pin on the ways 25. A bar 42 is pivoted to the lower end of the latch 41 and is fitted to swing freely in one direction, a shoulder'43 preventing it from moving toward the track 0. Alatch 44, pivoted to the plate 19, takes on a beveled stud 45 on an arm or bracket 46,

reduced to enter the slots 81.

secured to the plate-track C, and locks the plate 19 in position near the slot h. The bracket 46 is elongated and has a projection 47 on its outer end adapted to engage and trip the latch 41 as the carrier-plate 19 swings away from the track 0. This releases the carriage E, which is hung so that it will tilt into the position shown in Fig. 9 and the clamp-heads 34 projected thereby into the tank K.

A fan-escapement mechanism M is mounted on the top of the frame B, and is actuated by a spring 50 in the usual manner. A vertically-sliding bar 51, mounted on a standard 52, has its lower end reduced to enter a slot 53 in the scape-wheel 54. An arm 55 onthe bar 51 projects downward into engagement with the fan 56. A horizontal lever 57 is pivoted in a standard58 on the bottom of the frame, and has its short arm connected by a vertical rod 59 with the arm 51 of the escapement. A counterbalance-weight 60 is mounted on said short arm of the lever, and its long arm is provided with a table or pan 61, disposed in position to receive a coin from the coin-chute 62, which leads from the slot b in the case. The lever 57 is actuated by the weight of the coin to release the escapement M. A crank is secured to the arbor of the scape-wheel 54. A stub-shaft 66 is journaled on the frame and bears a fork 67, adapted to engage the arms 29 and 30 on the carriage and force the clamp-heads 34 into the plateslot h. A crank 68 is secured to the stubshaft and connected with the crank 65 by a lever 69. A vertical rod 70 slides in eyes on the frame and has a head 71, adapted to be engaged by a cam 72 on the scape-wheel arbor, whereby the rod is elevated. A bellcrank lever 73 is pivoted on the frame near the counter-balance 60, and has one arm connected with the rod 70 by a lever 74.

A worm escapement mechanism R (best shown in Fig. 5) is mounted in the frame below the tank K and at the rear of the platecarrier track 0. Said escapement R is mounted in vertical frame-plates 74, and is actuated when released by a coiled spring 75, in the usual manner driving the main shaft H by vmeans of a beveled gear 76, mounted on the arbor 77 of the scape-wheel 78. This gear meshes with a corresponding gear 79 on a sleeve 80, loose on said shaft between a collar 94 and shoulder 95, as shown in Fig. 6. The wheel 78 has two diametrically-opposite slots 81 in its periphery. A vertical rod 82 slides in a bracket 83 on the frame-plate 74, its upper end being beveled at 84 and its lower end A bell-crank lever 85 is pivoted to an arm on said bracket, and has one arm connected with an arm of the bell-crank 73 by a rod 86. The opposite arm of the lever 85 is connected with an angle-rod 87, secured to the sliding rod 83 and projecting into the path of a rotary arm or fan 88 on the arbor of the gear 90, which meshes with the fan-worm 91 of said escape- IIS Figs. 2 and 3.

ment. bar 82, said latch having a beveled upper end and a notched lower end adapted to engage the bracket 83 and lock said bar when elevated. An eccentric 93 (see Figs. 2 and 3) is mounted on the scape-wheel arbor 7 7 between the beveled gear 76 and frameplate 74 and actuates a horizontal rod 96, sliding in a bracket 97 on the plate-track O. This rod actuates the escapement mechanism T (shown in Fig. 10) for the plate-carrier D.

The escapement consists of an angle-rod 98, which slides laterally in ears 99 on the inner face of the track 0, (see Fig. 10,) and is provided with a boss or stud 100, which engages the studs on the carrier D and supports it. A vertical rocking shaft 101 is mounted in the bracket 97 and an arm 102 on the track C. Crank-levers 103 connect the upper end of the shaft with the angle-rod 98, whereby said rod may be intermittently moved to engage the alternate studs 1 on the carrier. Crank-rods 104E connect the lower end of the shaft with the eccentric-rod 96.

A flanged sleeve 105 is set-screwed onto the shaft H, its flange 106 being parallel with a companion flange 107 on the loose sleeve 80 on said shaft. A cam 108 is mounted on the flange 107, and a dog 109, pivoted to said flange, engages a stud 110 (see Fig. 3) on the flange 106, causing the shaft H to rotate when the gears 76 and 79 move the sleeve 80 in one direction or from left to right as viewed in A lever 111 is pivoted on a standard 112 on the frame and projects into the path of the cam 108, and is adapted to engage the dog 109, freeing it from the stud 110, and release the sleeve 80 to permit the shaft H to be returned. A coiled spring 113 connects said lever with the standard and causes it to strike the dog after passing the cam with sulficient force to disengage said dog from the stud. A stitl' coiled spring 114 has one end secured to an arm 115 on the frame-plate 74 and is coiled around the shaft H, to which it is secured, said spring serving to return the shaft when the sleeve 80 has been released, as described. A ratchet-wheel 116 is mounted loosely on the shaft ll above the plate 19 and is engaged by a pallet 117 on a spindle 118, mounted in a bracket 119 on the frame, said spindle also bearing a fan 120. The ratchet 116 rests upon a ratchet-wheel 121, set-screwed to the shaft H. A springpawl 122 on the ratchet 116 engages the ratchet 121,and is arranged to slip thereon as the gears rotate the shaft H and to connect the ratchets to restrain the movement of the shaft when returned by the spring 114. The shaft when rotated by the escapement R carries the plate 19 and carriage E away from the track 0. When said carriage arrives over the last tankcompartment, a pawl 125 (see Fig. 5) on the under side of the plate 19 near said carriage engages the upper end of the scape-rod 82 and locks said plate, preventing its return until said rod descends. The beveled ends 37 of A latch 92 is pivoted to the sliding the carriage-clamp arms 33 and 3a are now disposed between the arms (see Fig. 5) of a scissorslever 126, pivoted in abracket 127 on the track 0. Rods 128 are respectively pivoted to the lower ends of the lever-arms and have their lower ends pivoted to a rod 129, fitted to slide vertically in brackets 130 on the track 0. A lever is pivoted to the frame-plate 74:, one arm thereof projecting into the path of two cams 136 on the scapewheel 78, which alternately engage and lift said arm. The outer arm of the lever is pivoted to the rod 129, which is drawn downward as said lever is moved by the cams, closing the scissors-lever onto the ends of the clamparms and separating the clamp-heads 3 1. A coiled spring 137 connects the rod 129 with a bracket 130 and acts contractively to return said rod and open the levers 126 after the lever 135 is released from the cams 136.

A shutter 151 (see Fig. 1) is fitted to slide across the lens-tube opening 152, and is mounted on an arm of a lever 153, pivoted on the tubes. A contractile spring 151 connects said arm and tube. A small lever 155 is pivoted on the inner end of the lever 153, and a coiled spring 156 connects one arm thereof with said lever. Arms 157 on the fork 67 above the carriage E engage an arm of the lever 155 and move the shutter 151 to expose the sensitive plate as said fork moves to advance the clamp into the plate-slot 7L. The end of the lever 155 is beveled to permit the arm 157 to slip by after making the exposure and the spring 154: to close the shutterbefore the clamp grasps the sensitive plate.

In the use of my improvement a coin is inserted in the slot 1) of the case and passes down through the chute 62 onto the table or pan 61. A slot 150 (see Fig. 2) is formed in the bottom of the chute to prevent coins of smaller denomination than those for which the chute is designed from falling onto the pan. The long arm of the lever 57 being depressed by the weight of the coin, the bar51 is forced upward thereby and the escapement M released. The scape-wheel 54, rotating, actuates the fork 67 and opens the shutter 151 to make the exposure, as above described. The fork then engaging the arm 30 of the carriage-clamp, projecting the clamping-heads into the plate-slotat each side of the plate, at which point the latch 38 strikes a stud 160 on the carriage, freeing the clamparms 32 and 33, which are at once separated by their spring, and the heads 3i caused to grasp the plate g. of the escape-wheel 54 now elevates the rod 70, actuating the bell-crank lever 73. Said lever, being connected with the bell-crank lever 85, moves it to elevate the rod 82 and release the escapement mechanism R. Said mechanism being at once set in motion by its spring 75, the shaft H is thereby rotated and the carriage E begins to travel away from the plate-track C, carrying the sensitive plate g, which has been withdrawn from the carrier The cam 72 on the arbor by the contractile spring 35, said spring cau'sing the clamp to follow the forkas it is returned by its crank. The different compartments of the circular tank K are filled with the various solutions employed to develop the plate As the carriage advances, the latch 41 engages the stud 47, and is released therefrom, when it immediately tilts by its own weight into the vertical position shown in Fig. 9. The plate g is thus immersed in the first liquor 161, as shown in said figure. At each partition 18 a cam 162 on the rim of the tank engages the bottom of the carriage and elevates it sufliciently to enable the plate g to pass over said partition, when it drops into the bath in the succeeding compartment. When the scape-bar 82 is elevated, as described, the latch 92 (see Fig. engages the bracket 83 and prevents said bar from dropping back into the slot 81 in the scape-wheel 78. The weight end 21 of the carriage-plate 19 engages said latch as it passes and frees the bar 82 therefrom, so that it drops onto the periphery of the scape-wheel 78 in position to fall into the succeeding slot 81 and stop the mechanism. An elongated cam 164, (see Figs. 3 and 4,) disposed on the tank near the end of the tank, tilts the carriage into a horizontal position, in which it is locked by its latch 41. As soon as the carriage E reaches a the bar 82 its pawl 125 passes over the beveled end 84 of said bar and locks the carriageclamp-heads 34, which are disposed opposite the plate-chute 17, when the carriage is locked on the bar 82 and permits the finished picture to fall into said chute, through which it is discharged from the case. Meanwhile, at about three-quarters of the complete revolution of the shaft H, or approximately at the time when the lever 135 is engaged by the cam 136 on the scape-wheel 78, the lever 111, striking the pawl 109 on the flange 107 on said shaft, disengages it from the stud on the flange 106 and unlocks the sleeve 80, so that the shaft may be returned by the spring 114, said shaft being now held from so returning by the scape-bar 82. At the completed semi-revolution of the shaft 77 said bar falls into the opposite slot 81 in the scape-wheel. The eccentric 93 on the shaft 77 hasmeanwhile moved the rocking shaft 101 and drawn the anglebar 98 from right to left, as viewed in Fig. 10, disengaging its stud 100 from the carrier-stud 1 and placing it in position to engage the succeeding stud 1. The carrier falls when thus released until stopped bysaid bar, when another sensitive plate 9 is adjusted in the opening f of the carrier-track. The shaft H being freed, as described, the spring acts at once to return said shaft, and with it the carriage, toits original position, as shown in. Fig. 3, where it is locked by the latch 44 on the stud 45. The carriers D following each other from the feed-box F into the track 0 a constant supply of plates gisafforded,

bar and released the main escapement R the bar 51 re-enters the slot in said wheeland stops said escapement until again released by a coin. By releasingthe main shaft H prior to the completion of a revolution, as described, the entire power of the escapementR during the remainder of the semi-revolution of its shaft 77 is applied to operating the scissorslevers 126, considerable force being necessary to overcome the spring-tension of the clamping-arms and release the picture.
